Answer: 1.) y = x + 11
2.) y = -2x + 5
Step-by-step explanation: Use the values in the chart to calculate the slope: difference in y-values divided by difference in x-values.
Then take the calculated slope, substitute for <u>m </u>in the point slope form of the equation, choose any pair of values in the chart, substitute for y and x in the equation and solve for b.

Answer: 920</h3>
=================================================
Explanation:
The front face is a triangle with area of base*height/2 = 15*8/2 = 60 square feet.
The back face is identical to the front face, so we have another 60 square feet.
The left rectangular wall is 20 ft by 8 ft tall. Its area is 20*8 = 160 ft^2
The right slanted rectangular face is 20 ft by 17 ft. Its area is 20*17 = 340 ft^2
Lastly, the bottom rectangle floor is 15 ft by 20 ft to give an area of 15*20 = 300 ft^2
------------------
To summarize so far
- Front face = 60 ft^2
- Back face = 60 ft^2
- Left face = 160 ft^2
- Right slanted face = 340 ft^2
- Bottom floor = 300 ft^2
Add up those areas to get the overall surface area.
60+60+160+340+300 = 920
Volume of cylinder = πr^2 × h
= π × (5/2)^2 × 13
= 255.25 yd^3
105x=6.50 (first ride)
30x=9 (second ride)
105x+30x=6.50+9
Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27
